IMPROVEMENT IN LOG-TURNERS.

Specification forming part of Letters Patent No. 140,386, dated July 1,1873; application filed April 19, 1873.

To all whom it may concern:

Be it known that I, ISAAC W. POOL, of Eau Claire, in the county of EauClaire and State of Wisconsin, have invented a new Improvement inLog-Turners; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings making part of this specification, in which-Figure l is a sectional view of the frame in which my turner is applied,representing the turner in a vertical position. Fig. 2 is a versectionthrough the turner detached from its frame. Fig. 3 is a top view of theframe of Fig. 1, representing the turner in a horizontal position.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to provide means for moving a log intoposition on the saw-carriage, and against the knees thereon, and alsofor turning the log while on the carriage, as will be hereinafterexplained.

The following description of my invention will enable others skilled inthe art to understand it:

The log-turner which I am about to describe will, in practice, bearranged in front of the saw-carriage,and about the center thereof, soas to move the logs upon the carriage against the knees or brackets, andto turn them when desired. I

In the accompanying drawings, A represents the frame which supports theturner B, and C represents an'iendless chain applied between the twoside plates of the turner, every other link of which chain isconstructed with a pointed tooth or spur, p, for the purpose of turninga log. I This spurred chain C is passed around two' rollers, e e, thelower one, 0, of which is keyed on a shaft, f, which carries on one enda wheel, 0, outside of the turner, which wheel engages with a wheel, 0,of corresponding diameter, on a shaft, 9. The shaft 9 carries on one enda belt-wheel, P, to which motion can be communicated from any convenientshaft of the main driving-power of the mill, and at the will of theoperator. On this shaft the turner B is allowed to vi brate freely,which vibration is given to it by means of a lever, L, on a rock-shaft,i, on which shaft is keyed a toothed segment, h, the teeth of whichengage with the teeth of a segment 1), formed on the turner B. Bypivoting the log-turner B on the shaft '9, and employing a segment, h,on an oscillating shaft, i, on which is a hand-lever, L, the operatorcan adjust the turner in a horizontal position, as indicated in Fig. lin-dotted lines, and in Fig. 2, in full lines, in which position of theturner a log can be rolled over it upon the floor or top of frame A thenby moving the lever Lthe free end of the turner can be raised, whichoperation will move the'log forward and against the knees of thecarriage. After moving the log in proper position upon the carriage itcan be turned at will by rotating the shaft 9.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

l. The spurred chain C, applied to a log mover and turner, B, which isapplied loosely on a shaft, 9, in combination with wheels 0 c,substantially as described.

2. The toothed segment b on the vibrating log mover and turner B, incombination with the toothed segment h on the shaft 6 of lever F,substantially as described.
